Zhuzhou Grewin Tungsten Carbide is engaged in manufacture and export wide range of tungsten carbide tools, wear parts and components in different industries. We produce carbide rod with HIP sintered, h6 grind. Standard length 330mm, Solid carbide rods, rods with single hole, double holes. Our good prices, quality and services are waiting for you.
1. Using low-pressure sintering technology, the quality is stable and reliable: the maximum sintering pressure can reach 100 kg, the internal pore of the alloy can be effectively eliminated, thus obtaining compact high hardness and high strength blanks, and advanced temperature control system can effectively reduce the quality fluctuation.
2. With the over-pressure auto-relief extrusion equipment, all types of bars can be produced: the imported auto-extrusion equipment from Germany can be used to regulate the pressure according to different requirements, which is conducive to the production of different types of bars.
3. Precision grinding of bars with high precision can achieve
mirror effect: CNC grinder has the largest polishing speed, which
can quickly remove the damaged layer caused by polishing, improve
the surface finish, and achieve the maximum mirror effect.
Precision of precision grinding bar: Diameter tolerance D < 0.03
length tolerance L < 0.5.
Scope of use:
1. Making PCB micro-drill, cemented carbide bit, cemented carbide end milling cutter, cemented carbide reamer and other tools.
2. Used for processing aluminium alloy, stainless steel, heat-resistant alloy steel, ductile iron, nickel-based and titanium alloy, non-ferrous metals and other products.
3. Making plug-ins of various shapes, silicon steel sheets and cold rolled sheets, stainless steel punches, thimbles and punches.
4. Making carbide carving cutter, carbide tap, carbide rotary file, etc.
5. Making cemented carbide grinding rod.
